Description

Strap Field of invention

The present invention relates to a watch or the like for attaching a link member for forming a watch band.

Background of the invention

Fig. 30 (a) is a perspective view showing the prior art. Figure 30 (b) is a plan view showing the prior art of Figure 30 (a) from above. Figure 30 (c) is a plan view showing the prior art of Figure 30 (a) from below. Fig. 31 (a) is a perspective view showing the prior art. Fig. 31 (b) is an exploded perspective view showing the prior art of Fig. 31 (a). Fig. 31 (c) is a plan view showing the prior art of Fig. 31 (a) as seen from above. Figure 31 (d) is a plan view showing the prior art of Figure 31 (a) from below. Fig. 32 (a) is a perspective view showing the prior art and seen from the inside. Fig. 32 (b) is a partially enlarged perspective view showing the inner surface of Fig. 32 (a).

In the prior art, the structure of the link member of the watch band is known as: (1) a maker who performs press working, forging, or cutting (hereinafter referred to as "solid (non-scale) type).) (3) A solid (non-scale) material is combined (hereinafter referred to as "individual type"). (3) A plate-shaped member is formed by pressing, bending, molding, etc. (hereinafter referred to as "sheet type" (4) The member in which the plate member is wound around the integrally formed link member (hereinafter referred to as It is "rolled type". )Wait.

In the wristwatch strap or the like, the link member to be connected is preferably a three-dimensionally thick appearance. Therefore, as shown in FIGS. 30(a) to (c), the "solid" link member 110 in which the outer link portion 102 and the middle link portion 103 are integrally formed by press working or forging processing or the like is known. . In recent years, the focus has been on the design of the watch case or watch strap, and it has to be strengthened in the watch itself. Therefore, in order to recognize that the outer link portion 102 and the middle link portion 103 are formed of different members, the outer link portion 102 and the middle link portion 103 are subjected to different surface treatments or processes to achieve a high-grade feeling of the band. However, in the "solid type" formed integrally, the outer link portion 102 and the middle link portion 103 cannot be easily and inexpensively recognized as different members, and in order to be in the outer link portion 102 and the middle link portion 103. The surface treatment or processing is performed separately, so the processing cost is high. Therefore, in the "solid type" link member 110, the sense of quality is gradually not obtained.

In order to solve such a problem, there is known an "individual type" link member 120 in which solid materials are combined as shown in Figs. 31(a) to (d). In this case, the outer link portion 122 and the middle link portion 123 are separately produced and combined. As shown in Fig. 31 (b), the two outer link portions 122 located on the outer side in the width direction are connected to each other by the connecting piece 125 on the back side. The middle link portion 123 is provided with a step portion 124 for fitting to the connecting piece 125, and the pin 160 is inserted into the pin hole 170 of the middle link portion 123 by the pin 160, and the outer link portion 122 is coupled with the middle link portion 123. . Thereby, the outer link portion 122 and the middle link portion 123 can be made to be individual members, and a three-dimensional and heavy appearance can be obtained, and the outer shape is good. However, in the complex link shape in which the two outer link portions 122 and the connecting piece 125 are integrated, It is necessary to perform processing with high processing precision and cost, and the processing steps are also complicated and complicated, and sometimes the quality stability cannot be obtained.

In this case, in the "sheet type", since the assembly portion for manual work is reduced in cost, a number of prior art techniques such as Patent Documents 1 to 5 are known. In Patent Document 1, one link member is connected by folding one flat plate into three solid pieces. Although the side surface in the width direction of the band is polished, the boundary of the overlapped sheets is not conspicuous, but the impression of the high-grade product of the solid material cannot be obtained. Further, since the wound piece for joining the link member group exhibits a seam on the back surface, there is sometimes a problem that the wrist is scratched by the burr of the seam. Patent Document 2 also has a portion in which the uneven portion is engaged on the back surface of the link member, and has the same problem as Patent Document 1.

In the case of the patent document 3, the bending joint portion is also invisible, but in the same manner as in Patent Document 1, the boundary between the overlapping sheets is exposed on the side surface in the width direction of the band, and the impression of the high-grade product of the solid material cannot be obtained. Patent Document 4 is a sheet in which one of the linked link members is fitted to form a rigidly joined sheet between the front edges of one flat plate, and the seam between the front end edges is sandwiched between the upper and lower sides of the flat plate. The sheet is welded and overlapped, but a problem similar to Patent Document 1 is generated. Patent Document 5 also exposes the boundary of the overlapping sheets on the side surface in the width direction of the band, and presents the same problem as Patent Document 1.

In order to solve such a problem, the "wrap type" in which the link member is wound around the link member is known as the watch band of Figs. 32 and 33. This is a configuration in which one sheet-like member is wound around the middle link portion of the solid link shown in FIG. As shown in FIG. 32 and FIG. 33, the plate-like structure wound around the middle link portion The end group of the piece has a seam on the back side, so there is a problem that the corner of the end or the burr may scratch the skin of the wrist when wearing the watch. Due to the seams on the back, there is also a lack of high-grade appearance.

In the case of the "winding type", Patent Document 6 discloses an outer casing mounting link located at one end of the wristwatch band. The outer casing attachment link is attached to a wristband attachment portion of the wristwatch case, and is formed by covering a link body made of synthetic resin with an outer casing member made of a metal plate such as stainless steel. However, since both end portions of the outer casing member exist on the inner surface of the outer casing mounting link, they have the same problems as the wristwatch straps of Figs. 32 and 33.

Summary of invention

Provided is a watchband in which a plate member is partially wound around a link member to enhance design changes and to create a solid shape In the sense of high quality, it is difficult to recognize the seam of the plate-like member by the linked chain link member group.

The present invention is a watch band in which a plurality of link members can be coupled to each other by a rotary shaft, wherein at least one of the plurality of link members has a plate member and is wound by the plate member. a member to be wound, wherein the member to be wound has a side portion facing the adjacent link member, and at least one end portion of the plate member is disposed at an upper end and a lower end of the side portion in the thickness direction Between the ministries.

Since the joint of the plate-like member wound around the link member is located at a portion that is difficult to be recognized by the linked link member group, a high-quality feeling like a solid material can be obtained. In particular, when a precious metal of gold or platinum is used for a plate-like member, an extra effect is obtained which can obtain a beautiful appearance of a solid material. Moreover, the skin of the wrist or the like is not damaged by the hook or the burr wound around the end portion of the plate-shaped member of the link member, and the skin feels good. Further, since the surface treatment and surface finishing of the plate-shaped member wound around the link member can be performed independently of the link member, various design changes can be added, and a significant cost reduction can be achieved compared to the conventional technique.

Detailed description of the preferred embodiment

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the respective embodiments, the same reference numerals will be given to the same components, and the description thereof will be omitted. In the following, an embodiment of the present invention is described as an embodiment of a wristwatch for a wristwatch. However, the present invention is not limited to the wristwatch, and the present invention is also applicable to a wristband that can exhibit a design effect such as decoration. Further, in the following embodiments, the form of the link member is described in terms of a so-called base block, a convex shape, an H shape, an E shape, etc., but may be applied to other forms.

(First embodiment)

1(a) to 1(c) are perspective views showing the link member 10 according to the first embodiment of the present invention. Fig. 2 is a perspective view showing a first embodiment of the present invention.

As shown in Fig. 1(a), the first embodiment is a basic embodiment in which the shape of the link member 10 constituting the band 1 is a square shape in plan view. The link member 10 of this shape is referred to as a base block. As shown in Fig. 2, in the present embodiment, the plurality of link members 10 are coupled by a rotating shaft 4 into a band 1 which is rotatable with each other. The link member 10 is constituted by the link member base portion 11 in which the groove 11M is cut and the plate member 12. The plate member 12 is wound in the longitudinal direction of the band 1 of the link member base portion 11. In the link member base portion 11, the groove 11M around which the plate-like member 12 is wound is formed on the inner side in the width direction of the watch band so as to be laid in the longitudinal direction of the watch band, and is formed on the side between the back surface of the watch. It is formed on the inner side in the width direction of the watch band so as to advance in the vertical direction. The link member base portion 11 is a wound member that can wind the plate-like member 12. The plate-shaped member 12 wound around the link member base portion 11 is one piece in the present embodiment, but a plurality of pieces may be used in order to design the effect.

The depth of the groove 11M is generally the thickness of the plate-like member, and the upper surface of the link member 10 is formed in a planar shape having no step difference between the link member base portion 11 and the plate-like member 12. However, it is also possible to make the upper portion of the side of the plate member 12 slightly visible from the base member 11 of the link member, or the depth of the groove 11M may be deeper than the thickness of the plate member 12, and the plate shape may not be seen from the side. Member 12. The term "embedded" is used in the sense of including all three of the above forms. When the noble metal is used for the plate member 12, the portion on which the plate member 12 is wound is turned into a solid noble metal, and thus the upper portion of the side surface of the plate member 12 is sometimes seen. Further, the groove 11M of the link member base portion 11 may be provided only on either the upper surface or the lower surface of the link member base portion 11. Further, as will be described later, the groove 11M may not be provided in the link member base portion 11, but the plate member 12 may be entirely covered.

In each link member 10, the rotation axis 4 is oriented toward the width of the band The inserted through holes 5 are provided at two sides on the both sides in the longitudinal direction of the band, and the rotary shaft 4 is rotatably coupled to the adjacent link members 10. As shown in FIG. 2, the rotation shaft 4 is configured as a rotation member in a flat annular shape in the present embodiment. However, the rotation shaft 4 is not limited thereto, and may be formed in four corners in plan view. Further, when the plate-like member is wound in the longitudinal direction of the band 1, the folded-back axis forming the curved surface of the folded portion of the plate-like member is the same as the through-hole 5, and faces the width direction of the band.

In the watch band 1, all the link members 10 do not have to be configured to wind the plate-like member 12 around the link member base portion 11, as long as the plate-like member 12 is wound around at least one of the link member base portions 11. From the viewpoint of design, the link member 10 having the plate-like member 12 may be appropriately selected in the watch band 1 as in a non-adjacent manner. In the present invention, the member constituting the band by the rotation shaft 4 is a link member, and if the plate member 12 is wound around the link member base 11 and is not wound, both of them are The link member of the strap. The link member base portion 11 around which the plate-like member 12 is wound has side portions 11a and 11b (referred to here as side portions in the longitudinal direction of the watch band) opposed to the adjacent link member 10. At least one end portion of the plate-like member 12 is disposed at the upper end portion 11d in the thickness direction of the side portion 11a of the link member base portion 11 (the end portion in the longitudinal direction of the band in the groove 11M on the surface side of the link member base portion 11) The lower end portion 11e (the end portion in the longitudinal direction of the band in the groove 11M on the back side of the link member base portion 11). As described above, if the link member base portion 11 has a shape without the groove 11M, the end portions of the upper surface of the link member base portion 11 and the lower surface of the link member base portion 11 which are wound by the plate-like member 12 are The upper end portion 11d and the lower end portion 11e. Furthermore, the side portion 11b may be disposed to arrange the end portion. In the example of Figure 1(a), in the chain structure The side portions 11a of the base portion 11 are disposed at both end portions 12a and 12b of the plate-like member 12, and the plate-like member 12 is wound to cover the four faces (the front and back sides and the two side portions) of the central portion of the link member base portion 11. Further, the side portion of the link member base portion 11 is a side surface between the end portion 11d and the lower end portion 11e in the thickness direction of the link member base portion 11. (Further, the side portions 11a and 11b are the side faces of the link member base portion 11 in a state in which the plate-shaped member 12 is not wound. However, since Fig. 1(a) is a view in which the plate-like member 12 is wound, it is used for display. The portion of the link member base portion 11 inside the plate-like member 12 is shown, and the side portion and the lead wire are shown by broken lines. The other embodiments are also the same.)

The plate-like member 12 is formed to be bent from the upper surface or the lower surface side of the link member base portion 11 toward the side portion 11a or 11b side, and is connected to at least one end portion of the plate-like member 12. The end portion of the plate-like member 12 is disposed between the upper end portion and the lower end portion in a state in which the end surface thereof faces the lower surface side or the upper surface side. In the example of Fig. 1(a), the plate-like member 12 is formed in a shape curved from the upper surface side and the lower surface side of the link member base portion 11 toward the side portion 11a side, and is connected to the both end portions 12a, 12b. Both end portions 12a and 12b of the plate-like member 12 are disposed between the upper end portion 11d and the lower end portion 11e with their end faces 12t and 12u facing the lower surface side or the upper surface side. The end portions 12a and 12b and the end faces 12t and 12u may be arranged to face each other. The details of the end portions of the other plate-shaped members will be described later.

At least one end portion of the plate-like member 12 is disposed between the upper end portion and the lower end portion in the thickness direction of the side portion of the link member base portion 11, whereby the bent end portion opposes the link member to which the partition wall is coupled, It becomes difficult to see by hiding between the linked link members, and the appearance of the solid material can be obtained. Further, the joint of the plate-like member (portion at both end portions or one end portion of the plate-like member) is located at the side portion, and therefore there is no hook or burr due to the end portion of the plate-like member wound around the link member. It hurts the skin of the wrist and the skin feels good.

Further, since the surface treatment and the surface finishing of the plate-shaped member wound around the base portion of the link member are performed independently of the base portion of the link member, various design changes can be added, thereby achieving a large degree of comparison with the conventional technique. Cost reduction. In the case of a solid chain link, it is difficult to perform mirror surface processing only in the center portion of the link member. However, in the present embodiment, the mirror surface processing is performed first in a state where the other plate member 12 is straightly extended before being wound. After that, it can be wound again, and the processing and assembly work becomes quite easy. Further, the processing which can be performed in a state in which the plate-like member 12 extends straight is not limited to mirror processing, and various processing or surface treatment can be easily performed.

Thus, in the watch band or the decorative band, various design effects must be produced, and since the link member base portion 11 and the plate member 12 can be individually plated and etched separately, sandblasting satin finishing can be performed ( Pearskin-finish) or hairline processing, so it can be easily processed. Thereby, since the decorative effect of the link member base portion 11 and the plate-like member 12, which have been individually processed differently, can be clearly seen, the design aesthetics can be increased. Moreover, since the seam of the plate-like member 12 is located at the side portion, a high-grade feeling of the solid material can be brought about. When a certain amount of preliminary forming is performed before the plate-like member 12 is fitted into the link member base 11, the assembly can be simplified. When the plate member 12 is etched, an extra design effect can be obtained by forming the surface of the link member base portion 11 where the base can be seen.

The singular number, the plurality of marks, or the design aesthetics of the character 16, the symbol, the mark 17, the pattern, and the like shown in FIGS. 1(b) and 1(c) may be applied to the plate member 12. In Figs. 1(b) and 1(c), the protrusion is convex, but of course, it can be processed into a concave shape. The processing means can press the processing or the like so that the characters 16, marks, marks 17, and the like are raised to have irregularities. In the plate member 12, unlike the solid material, press working can be easily performed. Not only the press processing, labeling or design, but also by engraving, engraving, etching, laser processing, etc., the processing steps are performed separately by the plate member before being wound around the link member 11 of the substrate. Processing is sufficient, so it can be performed quickly and easily.

As described above, it is understood that various design changes can be added when the plate member and the link member are separated from each other. Of course, the link member base portion 11 or the plate-like member 12 may not be limited to a material such as a stainless steel material, a titanium material, or a synthetic resin. The points described in the first embodiment are basically the same as those in the embodiment described below.

(Second embodiment)

Fig. 3 is a perspective view showing a link member according to a second embodiment of the present invention. Fig. 4 is a plan view showing a second embodiment of the present invention. Fig. 5 is a perspective view showing a linked link member according to a second embodiment of the present invention. Fig. 6 is a cross-sectional perspective view taken along line A-A of Fig. 3; Fig. 7 is a perspective view showing a link member according to a second embodiment of the present invention.

As shown in Figs. 3 and 4, the second embodiment is a band 1 in which a plurality of link members 20 are coupled to each other by a rotary shaft 4. In the present embodiment, a band called a so-called convex link member 20 is connected to the same link member 20 group. The link member 20 is constituted by the link member base 11 and the plate member 12. The link member base portion 11 around which the plate-like member 12 is wound has a middle link portion 3 and two outer link portions 2 that are next to the middle link portion 3. The intermediate link portion 3 is located on the inner side in the width direction of the band, and the outer link portion 2 is located on the outer side in the width direction of the band, so that the adjacent link members 20 are coupled to each other. The outer link portion 2 protrudes from the middle link portion 3 along the longitudinal direction of the band. That is, as shown in the perspective view of FIG. 3, the middle link portion 3 protrudes forward, and the link portion 2 protrudes rearward from both sides. The shape of the link member 20 is not strictly convex in plan view, but is referred to herein as a convex shape. Further, in the present embodiment, the link member base portion 11 is formed integrally with the outer link portion 2 and the intermediate link portion 3. In the present embodiment, the front-rear direction of Fig. 3 is referred to as "front" and "rear" of the link member.

When the outer link portion 2 is formed to protrude rearward in the longitudinal direction of the band (first direction), and the middle link portion 3 protrudes forward (second direction) with respect to the outer link portion 2, the rotation axis 4 is disposed between a respective protruding portion of the outer link portion 2. Each of the intermediate link portions 3 is connected to each other in the longitudinal direction of the band, and the intermediate link portion 3 constituting each of the link member bases 11 is formed with a first side portion 3a located at the rear and a front portion The second side portion 3b. At least one end portion of the plate-shaped member 12 is disposed on the first side portion 3a of the middle link portion 3, but may be disposed on the second side portion 3b. As shown in FIG. 6 which will be described later, FIG. 3 is an example in which both end portions of the plate-like member 12 are disposed on the first side portion 3a of the middle link portion 3.

The plate-like member 12 is wound in the longitudinal direction of the band with respect to the middle link portion 3 constituting one of the link member base portions 11. Further, when the plate-like member is wound in the longitudinal direction of the band 1, the folded-back axis of the folded-back portion of the plate-like member faces the width direction of the band which is the same as the through-holes 5, 5' at the time of connection. In the present embodiment, the width of the plate member 12 and the middle link portion 3 is Similarly, the width of the plate-like member 12 may be narrower than the width of the center link portion 3 (see FIG. 10 described later), and a plurality of plate-like members 12 may be provided. In this case, the groove in which the plate-like member 12 is wound in the middle link portion 3 may be formed on the front and back sides in the longitudinal direction of the watch band, or the plate-like member 12 may be embedded (the side surface may also have a groove). ). In the band 1, it is not necessary to wind the plate-like member 12 at all of the link member bases 11, as long as the plate-like member 12 is wound at least one.

In the width direction of the band in the link member base 11, the through holes 5, 5' through which the adjacent link members 20 and the rotary shaft 4 pass are provided. As shown in Fig. 3, the through hole 5 is provided in the outer link portion 2, and the through hole 5' is provided in the middle link portion 3. As shown in FIG. 3, the rotary shaft member (connection pin) constituting the rotary shaft 4 is inserted through the through-hole 5' of the intermediate link portion 3 through the through-hole 5' of the intermediate link portion 3, and inserted through the outer link portion 2 Through hole 5. As shown in Fig. 4, in the present embodiment, a plurality of identical link members 20 are coupled to each other to form the watch band 1.

Referring to the prior art of Figs. 32 and 33, the end portion of the plate-like member wound around the base member of the link member exists on the back surface of the link member and is disposed at a position where the seam of the plate-like member can be recognized. The beauty of the heartwood cannot be obtained, and the hooks or burrs at the ends can also damage the skin of the wrist. On the other hand, as shown in FIG. 5, at least one end portion of the plate-like member 12 is disposed at the upper end portion 3d and the lower end portion 3e in the thickness direction of the side portion of the link portion 3 constituting the link member base portion 11. (see Fig. 6), the seam of the plate-like member wound around the base of the link member is hidden by the linked link member group and is difficult to recognize, and the middle link portion 3 can be as beautiful as a solid material. Furthermore, it does not harm the skin of the wrist. Further, if the width of the plate member 12 and the middle link portion 3 are the same, even In the portion near the end portion of the plate-like member 12, a slight force acts on the width direction, and the vicinity of the end portion abuts on the side of the inner side of the outer link portion 2, whereby the end of the plate-like member 12 does not exist. The part is deflected in the width direction and falls off. FIG. 6 shows a case where the both end portions of the plate-like member 12 are formed as a joint in the side portion 3a on the rear side (first direction) of the link portion 3 in the link member 20. On the other hand, FIG. 7 shows a case where the both end portions of the plate-like member 12 are formed as a joint in the side portion 3b on the front side (second direction) of the link portion 3 in the link member base portion 11.

Further, the side portion 3b on the front side as shown in FIG. 6 or FIG. 7 has a vertical surface 3s, and further has a slope 3p or a curved surface between the vertical surface 3s and the upper surface or the lower surface of the middle link portion 3. 3q. In such a manner, the end portion 3g on the upper surface side of the inclined surface 3p or the end portion 3h on the lower surface side of the curved surface 3q are the upper end portion and the lower end portion of the side portion 3b, respectively. The case where 3p is a curved surface and 3q is a bevel is the same.

For example, when the end portion of the plate-like member 12 is disposed on the inclined surface 3p, the end portion of the plate-like member is disposed on the lower surface of the base portion of the link member as compared with the prior art as shown in FIGS. 32 and 33. The ends become illegible and have the effect of damaging the skin of the wrist due to the hooks or burrs of the ends.

The reason for this is that the end portion of the plate-like member 12 disposed at the inclined portion such as the inclined surface 3p is generally recognizable from the oblique direction, and is located at a portion which is more recessed than the upper surface.

However, it is preferable that the end portion of the plate-like member 12 is disposed on the vertical surface 3s as described above. Further, the end portion of the plate member 12 is disposed on the inclined surface 3p In the case of the curved surface 3q, the above-described effect of being disposed at a position closer to the vertical surface 3s than the upper surface or the lower surface of the middle link portion 3 is preferable, which is preferable.

As shown in Fig. 6, by arranging the end portion of the plate-like member 12 in the side portion 3a of the middle link member 3 recessed in the longitudinal direction of the band, even if the portion is viewed from the side in the width direction of the band, It is also hidden by the outer link section 2 and is difficult to recognize. Further, as shown in Fig. 7, the end portion of the plate-like member 12 is disposed on the side portion 3b of the middle link portion 3 which protrudes in the longitudinal direction of the band, and is in the form of a plate as compared with the state shown in Fig. 6. The member 12 becomes easy to wind and improves assemblability.

In the case where the link side of the link member 3 is directed toward the mounting portion of the wristwatch portion, the joint between the both end portions of the plate member 12 exists on the rear side of the link portion 3 in FIG. In the case of the 1st direction, when the watch is worn, the seam is located on the opposite side of the watch case in each of the link members 20. When the pointer or the dial is recognized, the seam becomes a dead angle and is difficult to see.

Further, in this case, as shown in Fig. 5, even in a state where the link member 20 is rotated about 30 degrees between the link members 20, as shown in Fig. 5, the link side portion 3 in the front side is located on the rear side. The side portion 3a of the (first direction) is hidden by the portion between the side portion 3b on the front side (second direction) of the link portion 3 and the back surface from the rear side. Further, the link members 20 are connected to each other at an angle of about 30 or more, and even if they are rotated by an angle of 30 or more from the state of FIG. 5, the link portions 3 in the front side shown in FIG. The side portion 3a located on the rear side (first direction) is hidden by the back side of the front side (second direction) of the link portion 3 on the rear side. Therefore, by arranging the end portions 12a and 12b of the plate-like member 12 in the side portion 3a on the rear side (first direction) of the middle link portion 3, regardless of the angle of rotation between the link members, Both ends 12a, 12b are hidden by the link members of the partition. This is because the chain link portion 3 in the rear side is a rotation axis that links the link portion 3 between the link portion 3 and the rear side in the front side, and the side portion 3a of the link portion 3 in the front side. Prominent link shape (this is a convex shape).

Thus, there is a side portion which is more difficult to be recognized because of the mounting direction or the link shape with respect to the wristband of the wristwatch case, but a seam is provided on the side before the middle link portion 3, or after the middle link portion 3 The side seams can be set appropriately depending on the connection condition of the plurality of links. The position of the seam can be appropriately set by the method in which the plate-like member 12 is wound around the link member base portion 11, but it is mainly that the link member 20 or the outer link portion 2 that is set to be connected to the partition wall is difficult to be recognized from the inside and the outside. No damage to the position of the wrist skin. The seam position of the plate-like member satisfying such a condition may be between the upper end portion and the lower end portion of the side portion 3a or 3b of the base portion of the link member.

As a result of research and development, the relationship between the link status of the complex links and the identification status of the joints has the following results. When the link member 20 is convex and the end portion of the plate member 12 is located at the side 3a on the rear side of the middle link portion 3, the thickness of the link member including the thickness of the plate member 12 is about 3 mm to 5 mm. In the range of the connection, when the gap between the surface of the plate-like member 12 wound around the middle link portion and the surface of the plate-like member 12 wound around the link portion 3 in the partition wall is 2 mm or less in total, it is known that Even when viewed obliquely as shown in FIG. 5, the link portion 3 in the rear side hinders the identification of the end portion of the plate-like member 12 wound around the link portion 3 in the front side, and simply allows The seams became unrecognizable.

The plate member 12 is formed to be in a table from the base member 11 of the link member The surface or the lower surface side is curved toward the side portion, and is configured to be coupled to at least one end portion of the plate member 12. The end portion of the plate-like member 12 is disposed between the upper end portion and the lower end portion of the side portion of the middle link portion 3 in a state in which the end surface thereof faces the lower surface side or the upper surface side. In the example of Fig. 6, the plate-like member 12 is formed in a shape curved from the upper surface side and the side surface side of the link member base portion 11 toward the side portion 3a side, and is connected to both end portions 12a and 12b. The end portions 12a and 12b of the plate-like member 12 are disposed between the upper end portion 3d and the lower end portion 3e with their end faces 12t and 12u facing the lower surface side or the upper surface side. The end portions 12a and 12b and the end faces 12t and 12u may be arranged to face each other. Next, the details of the winding of the plate member 12 toward the link member base portion 11 will be described. Further, in order to facilitate understanding of the portion formed on the plate-like member 12, the end faces 12t and 12u are also illustrated in Fig. 8(a) which will be described later.

8(a) to (d) are cross-sectional views taken along line A-A of Fig. 3, respectively. 9(e) to (h) are cross-sectional views taken along line A-A of Fig. 3, respectively.

Next, various embodiments of FIGS. 8 and 9 (a) to (h) are provided so that the plate-like member 12 faces the link member base portion 11 in the longitudinal direction of the band 1. Of course, the winding method is not limited to only these methods. Further, the link member base portion 11 has the shape of the first embodiment or the intermediate link portion 3 and the outer link portion 2 as shown in the embodiment of Fig. 2, and the shape described later in the third embodiment to be described later. However, the description herein can be applied to the shapes in the respective embodiments.

Here, the middle link portion 3 constituting one of the link member base portions 11 in the second embodiment is exemplified, and the reference numeral 11 is used.

Fig. 8(a) shows the arrangement of the end portions 22, 22' of the plate member 12. The plate member 12 is wound toward the link member base 11 when the side portion is located between the upper end portion and the lower end portion in the thickness direction. The fitting portion of the plate member 12 will be described later with reference to FIG. Here, the both end portions 22 and 22' of the plate-like member 12 are linear and do not have a fitting portion to be described later.

8(b) and 8(c), when at least one end portion 22 of the plate-like member 12 is disposed between the end portion and the lower end portion in the thickness direction in the side portion, the plate-like member 12 is wound toward the link member base portion 11. The way. In the aspect of Fig. 8(b), the one end portion 22 overlaps the other end portion 22', and the other end portion 22' is hidden inside the plate-like member 12, and both sides exist on one side portion. In the aspect of Fig. 8(c), the one end portion 22 is exposed on the outer side of the plate-like member 12, but the other end portion 22' is disposed on the other side portion and is hidden inside the plate-like member 12 covering the portion. At least one end portion 22 of the plate-like member 12 is disposed between the end portion and the lower end portion in the thickness direction of the side portion, but the other end portion 22' is hidden in the plate shape as shown in FIGS. 8(b) and 8(c). The inside of the member 12 is unrecognizable. The other end portion 22' is not limited to these forms, and may be disposed at a position that is unrecognizable or difficult to recognize.

8(d) is a view in which the both end portions 22, 22' of the plate-like member 12 are disposed between the end portion and the lower end portion in the thickness direction of one side portion, and both end portions 22 of the plate-like member 12, 22' (the inner side is planed into a slope) is embedded in the groove 21 on the side of the trapezoidal shape. When the inner sides of both end portions are planed into a slope, when the wedge plug is pushed in (pressed in), the close joint of the both end portions 22, 22' can be easily performed, and the both end portions are hard to be separated.

Fig. 9(e) shows a state in which the respective end portions 22, 22' of the plate-like member 12 are covered to be separated from the inclined surface of the other side portion.

Fig. 9(f) shows a state in which the respective end portions 22, 22' of the plate-like member 12 are inserted to embed the grooves 21, 21 of the one side portion and the other side portion.

(g) of FIG. 9 is that the upper and lower plate-like members 12 and 12' are covered from the upper and lower sides of the link member base portion 11, and the respective end portions 22 and 22' are opposed to each other, inserted and embedded in one side portion and the other. The aspect of the grooves 21, 21 on one side.

(h) of FIG. 9 is that the upper and lower plate-like members 12 and 12' are pressed into the link member base portion 11 from the upper and lower ends, and the end portions 22 and 22' are inserted into the same as in FIG. 8(d). The aspect of the trapezoidal shaped grooves 21, 21 of the side portion and the other side portion. In (g) and (h) of Fig. 9, the plate-like member covering the upper surface side is the first plate-shaped member 12, and the plate-shaped member covering the lower back side is the second plate-shaped member 12'.

In (g) and (h) of Fig. 9, the end portions of the first plate-like member 12 and the end portion of the second plate-like member 12' are on the side portions, and the end portions 22, 22' are placed in the link member base portion 11 The groove 21 is formed in an L shape and opposed to each other. The end portions of the first plate-shaped member 12 and the end portions of the second plate-like member 12' may be flat or bonded to each other by bonding or welding. Further, the end portion of the plate member 12 may be directly fixed to the link member base portion 11 by bonding or welding.

10 to 15 are perspective views showing various winding methods of the plate-like member 12 in the link member according to the second embodiment of the present invention. Symbols and wires of the side portion, the upper end portion, the lower end portion, the groove, and the like are only illustrated in FIG. 10, which must be described, and are omitted in FIGS. 10 to 12, 14, and 15 in order to prevent the drawing from being too complicated.

The plate-like member 12 can be wound in the longitudinal direction, the width direction, or both directions of the band with respect to the middle link portion 3 or the outer link portion 2. The side portions of the present invention are not necessarily arranged only in the longitudinal direction of the watch band.

In the embodiment of Fig. 10, the width of the plate-like member 12 and the middle link portion 3 are the same. Unlike the embodiment of Fig. 3, the plate-like member 12 has the full width of the link portion 3 in the width direction of the band. The form of the middle link portion 3 is also wound in a short manner.

The embodiment of Fig. 11 is a compromise type of Fig. 3 and Fig. 10, and the plate-like member 12 is rolled in a part of the link portion 3 in a manner shorter than the full width of the link portion 3 in the width direction of the band. Around the middle link portion 3, in the other portion of the link portion 3, a shape in which the width of the plate member 12 and the middle link portion 3 are the same is formed. In the example illustrated in Fig. 11, the length of the plate-like member 12 in the width direction of the band is such that the mid-link portion 3 does not protrude from the outer link portion 2, and the middle link portion 3 is from the outer link portion. 2 The portion protruding toward the length of the strap is longer.

The embodiment of Fig. 12 is a form in which the plate-like member 12 is not wound around the center link portion 3 and is wound around the two sides or the one-side outer link portion 2 in the longitudinal direction of the band. Of course, the plate member 12 may be wound around both the outer link portion 2 and the middle link portion 3.

The embodiment of Fig. 13 is a form in which the plate-like member 12 is wound around the center link portion 3 in the width direction of the band. In the example illustrated in Fig. 13, the plate-like member 12 is wound around the intermediate link portion 3 from the outer link portion 2 toward the longitudinal direction of the band, and is located in the groove 3M in the width direction of the band. Both end portions of the plate-like member 12 are disposed on the side portion 3f in the width direction of the center link portion 3. When the plate-shaped member 12 is wound in the band width direction of the center link portion 3, the groove 3M formed on the front side and the back side of the link member base portion 11 in the width direction is wound in order to wind the plate-like member 12. The end portion is the upper end portion 3d and the lower portion of the link member base portion 11 End 3e. Further, when the middle link portion 3 does not have the shape of the groove 3M, the end portion of the upper surface and the lower surface of the link portion 3 in the width direction of the band in the plate-like member 12 is the upper end portion 3d. And the lower end portion 3e. The positions of the upper end portion and the lower end portion are also the same as those of the outer link portion.

The embodiment of Fig. 14 differs from the embodiment of Fig. 13 in that the link member 2 is wound around the chain member 2 in the width direction of the band on both sides or on one side. In the example shown in Fig. 14, the plate-like member 12 is wound around the portion of the outer link portion 2 that protrudes from the middle link portion 3 toward the longitudinal direction of the band.

In the embodiment of Fig. 15, the plate-like member 12 is wound around the middle link portion 3 in a cross shape in both the longitudinal direction of the band and the width direction of the band. The plate member 12 is formed in a cross shape. Further, the outer link portion 2 may be wound in a cross-shaped plate-like member. In the example of Fig. 15, the portion of the middle link portion 3 that protrudes from the outer link portion 2 in the longitudinal direction of the band is a plate-like member 12 wound in the width direction of the band.

In the aspect of FIGS. 13 to 15, the joint of the plate-shaped member wound around the link member is disposed at a position where it is difficult to be recognized due to the linked link member group. In other words, in the embodiment of Fig. 13, the end portion of the plate-like member 12 faces the side portion of the link portion 2 other than the joined partition link member in the side in the width direction of the band, whereby the plate member can be hidden. The seams. Further, in the embodiment of Fig. 14, the end portion of the plate-like member 12 and the side wall portion 3 of the connecting wall link member are opposed to each other on the outer side in the width direction of the band, thereby hiding the plate member. seam. The end portion of the plate-like member 12 in the longitudinal direction of the surface band of the aspect of Fig. 15 is disposed at the rear side in the same manner as in the second embodiment, and is hidden in the link portion 3 of the connected wall link member, and the width direction of the band is Plate member 12 The end portion is disposed in the front direction as in the case of the embodiment of Fig. 13, and is hidden in the outer link portion 2 of the connecting wall link member.

13 to 15, by limiting the range of rotation of the adjacent link members 20, even if the band is recognized from the side in the width direction of the band, the end of the plate member 12 can be The adjacent link portion 3 or the middle link portion 2 is often hidden and difficult to recognize. Further, in the case of Fig. 15, it is possible to easily impart a complicated decoration such as a cross shape as compared with the case where direct decorative processing is performed on the surface of the link member base portion 11.

Further, as shown in Fig. 12, when the plate-like member 12 is wound in the longitudinal direction of the band of the outer link portion 2, it is preferable that the end portion of the plate-like member 12 is disposed on the outer link portion 2 from the middle link portion 3 toward the table. The side of the belt that protrudes in the longitudinal direction. In this case, the outer link portion of the link member (not shown) connected to the front side of FIG. 12 protrudes toward the seam side than the swivel axis of the through hole of the link portion 3 shown in FIG. . Thereby, as in the case described with reference to Fig. 5, any portion from the side portion to the back surface of the protruding outer link portion of the partition wall is in a state of being opposed to the joint. Therefore, the seam of the plate member 12 can be hidden regardless of the state of rotation between the link members.

Fig. 16 (a) is a perspective view showing a fitting portion of a plate member. Figures (b) and (c) are front views showing the fitting portions of the plate-like members. Fig. (d) is a perspective view showing a fitting portion of the plate member. (e) is a front view showing a fitting portion of the plate member. Figs. (f) and (g) are perspective views showing the fitting portion of the plate member. These figures are perspective views of only the plate-like member 12, and the display of the link member base 11 is omitted.

Figure 16 (a) in the side of the link member base (not shown) Between the upper end portion and the lower end portion in the thickness direction, the both end portions of the plate-like member 12 are fitted to each other by the wedge-shaped fitting portions 13, 14 to prevent the link member 20 from being separated in the thickness direction. If it is prevented from being separated in the thickness direction, each of the fitting portions formed at both end portions of the plate-like member may have a shape that can be arbitrarily fitted, and the both end portions may not overlap each other. In Fig. 16 (a), the wedge type is as shown in Fig. 16 (b). When the plate-like member 12 is bent from the straight state to the shape shown in Fig. 16 and wound around the link member base 11, the rebound of the plate-like member 12 is usually caused, and the seam at both ends is separated. When the both end portions of the plate-like member 12 are fitted to each other by the wedge-shaped fitting portions 13, 14, it is possible to prevent the sewn slit due to such rebound. Further, in the case of the wedge type, even if the tension or the twist of the both ends of the plate-like member 12 acts, it is not separated by the wedge action.

In the state in which the fitting portions 13 and 14 are fitted to each other at both end portions of the plate-like member, the gap portion 15 is formed at one of the both end portions (or both). After the plate member 12 is wound and fitted to the link member base portion 11, when the surface of the plate member 12 to which the mirror surface processing or the like is applied is damaged or the like, the plate member 12 needs to be removed and replaced. The gap portion 15 is provided to detach the fitting portions 13 and 14 from the gap portion 15 and to detach the plate-like member 12 from the link member base portion 11. However, although it is a clearance part formed by the circular arc, it is not necessarily limited to this. As shown in Fig. 16 (c), the straight end portions of the fitting portions 13, 14 may be separated from each other to form the gap portion 15. Further, when the inner surface of both end portions of the plate-like member 12 is formed with a slope, and the front end of the blade or the like is inserted between the side portion of the link member base portion 11 and the inclined surface, the fitting portions 13, 14 are folded. It is easier to carry out when opening, so it is advantageous.

In the aspect of Fig. 16(d), as illustrated in (e) of Fig. 16, the embedded The joints 13, 14 are formed in a shape such as a nested puzzle. A gap portion 15 is formed in a part of both end portions of the plate member 12. The shape of the other fitting portions 13 and 14 may be a key shape. Even if the survey portion of the plate member 12 is formed in such a shape, it is possible to prevent the both ends from being separated from the link member base portion 11 by the rebound, and at the same time, the bulging caused by the twist or the stretch can be prevented. In the aspect of Fig. 16 (f), the fitting portions 13, 14 are formed in a waveform shape. The fitting portions 13 and 14 are formed in a shape that fits in the width direction and does not fit in the thickness direction of the band. Therefore, in this case, the deviation of both ends in the width direction of the band can be prevented. Both end portions of the plate member 12 are fixed to each other by adhesion or the like, or are fixed to the link member base portion 11. In this case as well, the gap portion 15 is formed in one of the both end portions, and a blade or the like is inserted therein, and the fitting portions 13, 14 are cleaved by peeling off the bonding or the like. In the aspect of Fig. 16(g), the both end faces of the fitting portions 13, 14 form a slope. In this case, the fitting portions 13 and 14 are not fitted in the thickness direction and the width direction of the band, but are fitted into the inclined surface of the fitting portion 14 to press the slope of the fitting portion 13 against the link member base portion 11 side. Does not protrude toward the partition link member. As in the case of Fig. 16 (f), both end portions of the plate-like member 12 are fixed by adhesion or the like, and a gap portion 15 is formed at one of the both end portions to be peeled off and peeled off. Further, since the inclined surface facing the inner direction of the fitting portion 14 can hook the front end portion such as the blade, it is effective when the fitting portions 13 and 14 are opened.

When the plate-shaped member 12 is wound and fixed to the link member base portion 11, if the both end portions of the plate-like member 12 are not formed into a fitting shape, press-fitting, vacuum-bonding, adhesion, convergence, and magnetic engagement can be utilized. , screw fixing, etc. Further, both end portions of the plate member 12 may be welded by laser or the like. If it is Figure 8, In the case of 9(a) to (h), or when the plate member 12 is wound around the link member base 11 as shown in Figs. 16(a) to (g), the plate member 12 can be formed into an easy roll in advance. By the shape of the winding, the processing step of winding the plate-like member 12 can be performed extremely without scale.

The fitting portions 13, 14 shown in Figs. 16(a) to (e) may be formed in opposite shapes to each other in a male-female relationship.

In the example shown in Fig. 16 (a) to (e), the fitting portion 14 disposed on the upper side in the thickness direction of the link member base portion 11 is convex, and is disposed in the link member base portion 11 in the thickness direction. The side fitting portion 13 is concave.

When the fitting portions 13 and 14 are formed in a male-female relationship, the fitting portion 14 disposed on the upper side in the thickness direction of the link member base portion 11 is concave, and is disposed in the thickness direction of the link member base portion 11. The fitting portion 13 on the lower side is convex.

The fitting portion 14 formed in the convex shape shown in Figs. 16(a) to (e) is a portion in which the length of the portion protruding toward the lower surface side in the width direction of the link member base portion 11 is smaller than the left side or the right side portion. The length is still long. The case of such a shape is that the central portion of the seam becomes long, and this is located closer to the lower surface in the base portion 11 of the link member.

On the other hand, when the fitting portions 13 and 14 shown in FIGS. 16( a ) to 16 ( e ) are formed to have opposite male and female relationships, the central portion of the seam having a long length is located near the base member 11 of the link member. The position on the upper surface side. Therefore, as shown in FIGS. 16( a ) to 16 ( e ), the fitting portion 14 and the fitting portion 13 are formed into a convex shape and a concave shape, respectively, as compared with the shape formed to be opposite thereto. Make the seams less visible.

Figure 17 is a cross-sectional view taken along line A-A of Figure 3 . Figure 18 is a cross-sectional perspective view taken along line A-A of Figure 3 . Figure 19 is a partial cross-sectional view taken along line B-B of Figure 18. Fig. 20 is a plan view showing a base portion of a link member according to a second embodiment of the present invention. Figure 21 is a partial cross-sectional view taken along line C-C of Figure 20.

FIG. 17 shows the step δ formed on the link member base 11 by the outer link portion 2 and the middle link portion 3. The depth of the step δ is generally the thickness of the plate member 12, and the upper surface of the link member 20 is formed in a planar shape having no step difference between the link member base portion 11 and the plate member 12. However, it is also possible to make the upper portion of the side of the plate member 12 slightly visible from the base member 11 of the link member, or the depth of the step δ is deeper than the thickness of the plate member 12, and the plate member 12 cannot be seen from the side. Upper side of the side. When the noble metal is used for the plate member 12, the portion in which the plate member 12 is wound is turned like a solid noble metal, and thus the upper portion of the side surface of the plate member 12 is sometimes seen. Either way, it can be made that only the lower surface of the plate member 12 cannot be seen from the side.

Generally, when the link member base 11 in which the outer link portion 2 and the middle link portion 3 are integrated is manufactured by press working or forging, the boundary R between the outer link portion 2 and the middle link portion 3 forms a rounded portion R. (also known as the R department). Therefore, the corner portion or the like of the lower surface of the plate-like member 12 hits the R portion and is rolled up in the direction of the arrow of Fig. 19 to deteriorate the finishing of the boundary.

In order to prevent such a situation of being rolled up, a groove S is formed on both the front and back sides of the center link portion 3 along the boundary between the outer link portion 2 and the middle link portion 3. The groove L is preferably a length that can be hidden by the outer link portion 2 as viewed from the side of the band. Thereby, as shown in FIG. 21, by the groove S, the corner portion of the lower surface of the plate-like member 12 does not hit the boundary between the outer link portion 2 and the middle link portion 3, and does not occur as shown in FIG. Rolled up.

Fig. 22 is a perspective view showing a link member according to a third embodiment of the present invention.

As shown in Figs. 22 to 24, the third embodiment is a band 1 in which a plurality of link members composed of two kinds of link members 30 and 40 are rotatably coupled to each other. In the present embodiment, the so-called H-shaped link member 30 is coupled to the link member 40 coupled thereto, and is coupled to the swing shaft 4 so as to be rotatable. The link member 30 has a middle link portion 3, two outer link portions 2 that are next to the middle link portion, and a plate member 12 that is wound around the middle link portion 3. The middle link portion 3 and the outer link portion 2 constitute a link member base portion 11. The middle link portion 3 is located inside the width direction of the band, and the outer link portion 2 connects the link member 30 and the link member 40 so as to be positioned outside the width direction of the band. The outer link portion 2 protrudes from the middle link portion 3 toward the front and rear sides in the longitudinal direction of the band, and the link member base portion 11 and the link member 30 are formed in an H shape in plan view. The link portion 3 having the plate-like member 12 wound has side portions 3a, 3b opposed to the adjacent link member 40. At least one end portion of the plate-like member 12 is disposed between the end portion of the side portion of the middle link portion 3 in the thickness direction and the lower end portion. In the example shown in Fig. 22, both end portions of the plate-like member 12 are disposed between the upper end portion 3d and the lower end portion 3e of the side portion 3a of the intermediate link portion 3. In the example shown in FIG. 22, both end portions of the plate-like member 12 disposed on the upper side and the lower side in the thickness direction of the middle link portion 3 are formed in a concave shape and a convex shape, respectively. The both end portions may be formed in a concavo-convex shape opposite to that of FIG.

The plate member 12 and the middle link portion 3 wound around the middle link portion 3 The width direction of the strap is the same width, but it may be shorter, and is formed as the link portion 3 in FIG. In the present embodiment, the number of the plate-like members 12 of the middle link portion 3 wound around the link member base portion 11 is one, but a plurality of strips may be desired for design effects. The form of various winding methods of the plate-like member 12 is the same as that of the second embodiment.

In the first and second embodiments, the watchband 1 is formed by connecting the same link member. However, as shown in Fig. 23, in the third embodiment, the plurality of link members composed of the two link members 30 and 40 can be mutually connected. The strap 1 is connected by rotation. The shape of the link member 40 connected to the link member 30 in the third embodiment is a substantially square shape as viewed in plan. In the form of Fig. 22, the plate member 12 is not wound around the link member 40, but the link member base is used as a link member. In the link member 40, the base block of the first embodiment of Fig. 1(a) around which the plate member 12 is wound may be used, and the chain link member 40 wound by the plate member 12 and the chain of the plate member 12 may be wound. The knot member 40 may take any consideration in view of the design effect of the watch band 1. As seen in the third embodiment, in other embodiments, the band member 1 may be formed by connecting the same link member, and the link member to be appropriately connected may be arbitrarily selected.

Each of the link members 30, 40 is provided with through holes 5, 5', and the rotary shaft 4 can be inserted into the adjacent link members 30, 40 so as to penetrate the width direction of the band. As shown in Fig. 22, the through hole 5 is provided in the link portion 2 other than the link member 30, and the through hole 5' is provided in the link member 40'. The rotary shaft member (the coupling pin) constituting the rotary shaft 4 passes through the through hole 5' of the link member 40 from the through hole 5 of the link portion 2 outside the link member 30, and penetrates the link member 30. The through hole 5 of the outer link portion 2 is inserted.

The link member 40 does not have the outer link portion. However, as shown in FIG. 24, the link member 40' may have the middle link portion 3' and the two outer link portions 2 of the middle link portion. 'Type. The center link portion 3' is located on the inner side in the width direction of the band, and the outer link portion 2' is located on the outer side in the width direction of the band, and connects the link member 30 and the link member 40'. The length of the outer link portion 2' in the longitudinal direction is shorter than the middle link portion 3', and the middle link portion 3' is forward and backward from the outer link portion 2' toward the length of the band along the longitudinal direction of the band. Both sides stand out. In this case, the plate-like member 12 may be wound around the middle link portion 3' or may be unwound.

In the present embodiment, at least one end portion of the plate-like member 12 may be disposed between the end portion and the lower end portion of the side portion in the thickness direction, and the seam of the plate-like member wound around the base portion of the link member may be It is difficult to recognize by the linked link member group, and the beauty of the solid material can be obtained. Further, since the seam of the plate-like member is located at the side portion, the wrist skin is not damaged by the hook or the burr of the end portion of the plate-like member wound around the base portion of the link member, and the skin feels good.

(Fourth embodiment)

Fig. 25 is a perspective view showing a link member according to a fourth embodiment of the present invention. Figure 26 is a plan view showing a fourth embodiment of the present invention.

In the fourth embodiment, as shown in Figs. 25 and 26, a plurality of link members 50 can be coupled to each other by the swivel shaft 4 so as to be rotatable with each other. In the present embodiment, a band called a so-called E-shaped link member 50 is connected to the same link member 50 group. Each of the plurality of link members 50 protrudes from the first link portion 7 in the first direction (the front side in FIG. 25) in the longitudinal direction of the band with respect to the second link portion 7, and the second link portion 7 is opposed to the first one. The link portion 6 is opposite to the first direction The second direction (the shape that protrudes in the back of FIG. 25. Among the one link member 50, the first link portion 6, the second link portion 7, the first link portion 6, the second link portion 7, and the first The link portion 6 is integrally formed in the same manner as in Fig. 18, and constitutes one link member base portion 11. The plate-like member 12 is wound around the second link portion 7 so as to cover the entire shape. The form of the mode is the same as that of the second embodiment.

Each link member 50 is provided with through holes 5, 5', and the rotary shaft 4 can be inserted into the adjacent link member 50 so as to penetrate the width direction of the band. As shown in FIG. 25, the through hole 5 is provided in a protruding portion of the first link portion 6 in the link member base portion 11, and the through hole 5' is provided in the protruding portion of the second link portion 7 in the link member base portion 11. . The rotary shaft member constituting the rotary shaft 4 passes through the through hole 5' constituting the second link portion 7 of the adjacent link member 50 from the through hole 5 of the first link portion 6 of the link member 50. The through hole 5 of the first link portion 6 reaches the through hole 5 of the first link portion 6 through the through hole 5' constituting the second link portion 7 of the adjacent link member 50. The second link portion 7 around which the plate-like member 12 is wound has side portions 7a and 7b (referred to as side portions in the longitudinal direction of the watch band) of the second link portion 7 constituting the adjacent link member base portion 11 . At least one end portion of the plate-like member 12 is disposed between the end portions 7a and 7b of the second link portion 7 in the thickness direction between the end portion 7d and the lower end portion 7e. In the example shown in Fig. 25, both end portions of the plate-like member 12 are disposed between the end portion 7d and the lower end portion 7e in the thickness direction of the side portion 7a. In the example shown in FIG. 25, both end portions of the plate-like member 12 disposed on the upper side and the lower side in the thickness direction of the second link portion 7 are formed in a concave shape and a convex shape, respectively. It can be formed in a concavo-convex shape opposite to that of FIG.

In the fourth embodiment described above, the link member base portion 11 is composed of 3 The first link portion 6 of the column and the second link portion 7 of the two rows are formed. The configuration of the link member base portion 11 may be the first link portion 6 of the four rows and the second link portion 7 of the three rows, or the first link portion 6 and the n- of the n columns. The second link portion 7 of one row (may be n is an integer of 3 or more). In other words, in the fourth embodiment, the base member base portion around which the plate-like member 12 is wound has the first link portion 6 of n rows and the second link portion 7 of n-1 rows, and is in the longitudinal direction of the band. The first link portion 6 that protrudes from the second link portion 7 in the first direction, and the second link portion that protrudes from the first link portion 6 in the second direction g on the opposite side to the first direction 7 is a shape that is alternately arranged in the width direction of the aforementioned band.

In the present embodiment, at least one end portion of the plate-like member 12 is disposed between the end portion and the lower end portion in the thickness direction of the side portion, and the seam of the plate-shaped member wound around the base portion of the link member is borrowed. It is difficult to recognize by the linked link member group, and the appearance of the solid material can be obtained. Further, since the seam of the plate-like member is located at the side portion, the wrist skin is not damaged by the hook or the burr wound around the end portion of the plate-like member at the base of the link member, and the skin feels good.

Fig. 27 (a) is a cross-sectional view of the link member cut in the width direction of the band when the both end portions on the back side of the link member have a shape that is curved in a curved shape. Fig. 27 (b) is an enlarged view of a portion E of Fig. 27 (a). Fig. 27 (c) is an explanatory view for explaining a shape in which both end portions of the back side of the link member are concave in a curved shape. Fig. 28 is a side view showing the link member of Fig. 27(a); 29(a) and 29(b) are explanatory views of a model cross section of the link member formed in Fig. 27(a).

Next, reference is made to FIG. 3, FIG. 27(a) to (c), and FIG. 28 as an example. An embodiment in which the inclined portion V at the both end portions on the back side of the link member 20 of the second embodiment has a cross-sectional shape that is curved in a curved shape is described. In the present embodiment, both end portions on the back side of the outer link portion 2 are formed in a cross-sectional shape having an arcuate shape with a radius r. The cross-sectional shape of the curved concave shape in Figs. 27(a) and (b) is R which is a drawing reference symbol, and is also referred to as "reverse R portion shape" hereinafter. The other parts are the same as in the second embodiment. As shown in FIG. 28, the shape of the reverse R portion is not limited to the shape of the reverse R portion in which the width of the inclined portion V is fixed or fixed in the longitudinal direction of the band, and may be formed in the length direction of the band, the width of the inclined portion V or The shape of the inverse R portion changes.

The link member constituting the conventional watch band has a shape in which the inclined portion V is not formed at both end portions on the back side, and the corner portion where the back surface and the side surface of the link member intersect each other is close to the corner. The band using the link member having such a shape is that the corner portion where the back side and the side face of the link member touch the skin to cause an uncomfortable feeling, and the skin which is pressed by the corner portion is recessed to leave a trace of the corner portion. On the other hand, in the present embodiment, in the state in which the wrist is worn with the wristband, the portion of the inclined portion V at the both end portions on the back side of the outer link portion 20 is separated from the skin, and the angular portion does not touch the skin. . Moreover, for the wrist that often touches the band, the contact area of the back of the outer link portion 2 to the wrist is reduced. Thereby, the burden on the skin that the strap touches can be reduced. Further, in order to further reduce the burden on the surface of the watch band, it is preferable that the link member 20 does not form an angular shape at the place where the skin member 20 touches the skin. Therefore, as shown in FIG. 27(b), the boundary portion U between the back surface of the outer link portion 2 and the inclined portion V is formed into a curved surface that does not protrude from the back surface of the outer link portion 2 and is smooth. Further, as seen from Fig. 27(c), when the finger W touches both ends of the back side of the link portion 2 other than the link member, the hand The front end of the finger is adapted to the shape of the concave R portion of the concave shape, and the sense of disobedience when there is no contact improves the touch. On the other hand, as described in Patent Document 7 or Patent Document 8, a band of a conventional technique in which both end portions on the back side of the link member are formed in a linear shape is formed. Such a strap is in contact with the tapered portion when the finger W contacts the tapered portion, or contacts the tapered portion in a state in which one of the surfaces of the finger is deformed into a planar shape. Therefore, these straps cannot obtain a feeling of fit that is felt when the finger W contacts the portion of the shape of the reverse R portion. Further, in the band of the prior art, when the portion of the shape of the reverse R portion is formed into a linear taper, the link member is processed into a taper by cutting and grinding. Therefore, the straps of the prior art require two to three steps for the processing of the cone, and one to two steps for the grinding. On the other hand, in the case of the reverse R shape of the present embodiment, the portion of the reverse R shape can be processed in one step by pressing.

When the outer link portion 2 is formed by press molding which is formed by a mold, the formation of the portion of the reverse R portion will be described. As seen in Fig. 29, the model itself is formed into a shape K (a shape in which the shape of the transfer reverse R portion) is formed, and the purpose thereof is to form an inverse R portion shape from the stage of molding. Further, with respect to the portions of the circular prints G and H of Fig. 29(a), in addition to the characteristics of press forming, it is assumed that the portion of the circular prints I and J of Fig. 29(b) does not become the corner portion R even if the mold side is not formed. A slight corner portion R is also formed in the outer link portion 2. However, in order to create a desired shape, as shown in the portion of the circle G and H of Fig. 29 (a), the model must have a corner portion R as a target value. The processing of the both end portions on the back side of the link portion 2 in the present embodiment is of course not limited to the press molding, but the press molding is preferable in terms of reduction in processing cost and processing time.

Further, in the present embodiment, the cross-sectional shape of the arc-shaped recess having the radius r is formed. However, the cross-sectional shape of the inclined portion V may be a cross-sectional shape having an arbitrary curved shape. In other words, in the present embodiment, a plurality of link members are coupled to each other by a swivel axis, and are characterized in that, at both end portions in the width direction of the band, on the back faces of the plurality of link members. The inclined portion V formed in a shape gradually thinning from the inner side of the link member to the side surface thickness is provided across the longitudinal direction of the band, and the cross-sectional shape of the inclined portion V is concave in a curved shape. Further, the boundary portion U (see FIG. 27(b)) of the back surface and the inclined portion V may be formed into a smooth curved surface that does not protrude from the back surface. This embodiment is applicable not only to the link member 20 of the second embodiment, but also to the above-described respective embodiments including the base block type of the first embodiment. For example, when the present embodiment is applied to the base block type link member, both ends of the back surface of the link member base portion 11 in the width direction of the band can be formed in a reverse R portion shape. Further, when the present embodiment is applied to the link member of each embodiment, the link member of each embodiment can be applied to the link member in which the plate member 12 is not wound, regardless of the presence or absence of the plate member 12.

In addition, the technical scope of the present invention is not limited to the above-described embodiments, and various modifications are possible in the above-described embodiments without departing from the gist of the invention. That is, the specific configuration of the embodiment is merely an example and can be appropriately changed.
